Planned Maintenance
An annual inspection and maintenance program is strongly recommended starting no later than one year after installation of the heat pump. In harsh environments or coastal areas, a bi-annual inspection is recommended. See the recommended inspection checklist.
DANGER
Failure to heed the following will result in injury or death.
- RISK OF ELECTRICAL SHOCK FROM ENERGY STORED IN CAPACITORS - MODELS EQUIPPED WITH VARIABLE FREQUENCY COMPRESSOR DRIVES STORE ELECTRICITY EVEN AFTER THE POWER HAS BEEN DEACTIVATED AT THE POWER BREAKER. Wait for 2 minutes after the shut down of equipment before servicing.
- Deactivate power while routing wiring to control board.
- Follow all National Electric Codes (NEC) and/or State and Local guidelines.
WARNING
Failure to heed the following may result in injury or death.
-
Annual inspection and service must be performed by a qualified heat pump specialist in order to prevent physical injury or damage to equipment. For tasks requiring handling refrigerant, an HVAC license is required.
